Addressed elsewhere in the thread. I could easily envision a Supreme Court decision based on reasoning such as, "Clearly the intent of the framers was that American citizens should not be forced to provide goods or services to the military against their will."
Dumber stretches of logic have certainly emerged from SCOTUS. If Wickard v. Filburn makes sense to them, so could this.
Maybe not from the present bench, but perhaps from a hypothetically less-partisan one.
